/**
* A default parser for MapReduce job configuration properties.
* MapReduce job configuration properties are represented as key-value pairs.
* Each key represents a configuration knob which controls or affects the
* behavior of a MapReduce job or a job's task. The value associated with the
* configuration key represents its value. Some of the keys are deprecated. As a
* result of deprecation some keys change or are preferred over other keys,
* across versions. {@link MapReduceJobPropertiesParser} is a utility class that
* parses MapReduce job configuration properties and converts the value into a
* well defined {@link DataType}. Users can use the
* {@link MapReduceJobPropertiesParser#parseJobProperty(String, String)} API to
* process job configuration parameters. This API will parse a job property
* represented as a key-value pair and return the value wrapped inside a
* {@link DataType}. Callers can then use the returned {@link DataType} for
* further processing.
*
* {@link MapReduceJobPropertiesParser} thrives on the key name to decide which
* {@link DataType} to wrap the value with. Values for keys representing
* job-name, queue-name, user-name etc are wrapped inside {@link JobName},
* {@link QueueName}, {@link UserName} etc respectively. Keys ending with *dir*
* are considered as a directory and hence gets be wrapped inside
* {@link FileName}. Similarly key ending with *codec*, *log*, *class* etc are
* also handled accordingly. Values representing basic java data-types like
* integer, float, double, boolean etc are wrapped inside
* {@link DefaultDataType}. If the key represents some jvm-level settings then
* only standard settings are extracted and gets wrapped inside
* {@link DefaultDataType}. Currently only '-Xmx' and '-Xms' settings are
* considered while the rest are ignored.
*
* Note that the {@link MapReduceJobPropertiesParser#parseJobProperty(String,
* String)} API maps the keys to a configuration parameter listed in
* {@link MRJobConfig}. This not only filters non-framework specific keys thus
* ignoring user-specific and hard-to-parse keys but also provides a consistent
* view for all possible inputs. So if users invoke the
* {@link MapReduceJobPropertiesParser#parseJobProperty(String, String)} API
* with either <"mapreduce.job.user.name", "bob"> or
* <"user.name", "bob">, then the result would be a {@link UserName}
* {@link DataType} wrapping the user-name "bob".
